A "Little Sis" restaurant has been opened as a prototype to test the concept of a smaller facility with a limited menu. Experience during the first two years was as follows:
The average sale is $10 per customer. Use the following partially completed graph to determine the break-even quantity graphically. Then refine your solution by solving it algebraically. (Show your work for credit.)
◦ The break-even quantity is more than 70,000 customer visits.
◦ The break-even quantity is more than 30,000 customer visits and fewer than or equal to 50,000 visits.
◦ The break-even quantity is more than 50,000 visits and fewer than or equal to 70,000 visits.
